  1. For a Na K pump, as per wikipedia's diagram, the binding of sodium opens an ATP binding site. ATP hydrolysis changes the pump conformation and releases the sodium. The new conformation binds potassium, which when bound, releases the phosphate and reverts the conformation starting it over again. What is the ATP hydrolysis step for? I understand that the kinase is moving the phosphate from ATP to the transporter, but is that required for a conformational change? would an ionic interaction or some other binding that doesn't involve chemical change work to change the conformation as we
